Hubble Telescope finds Water Vapour on Habitable-Zone Exoplanet

For the first time have Astronomers have discovered water vapour signatures in the atmosphere of a planet beyond our solar system that resides in the habitable zone (the region around a star which can support liquid water given sufficient atmospheric pressure). Discovery of Water Vapour in Habitable Zone The Astronomers from the Center for Space ..


Scientists discover water vapor in atmosphere of a super-Earth “K2-18b”

For the first time, the astronomers at the University College London have discovered water vapour in the atmosphere of an Earth-size planet called K2-18b. They used data from NASA’s Hubble Space Telescope. The exoplanet “K2-18b” is 8-times the mass of Earth and known as a super-Earth. It orbits a red dwarf star 110 light-years away ..


NASA discovers first nearby super-earth planet GJ357d

The NASA scientists have characterized the first potentially habitable world outside our own solar system that may be suitable for life. The super-earth planet — named GJ 357 d — was spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. It is estimated that planet is about six times the size of our planet and ..


The researchers at University of Warwick in UK discover a rogue exoplanet

The researchers at the University of Warwick in the UK have discovered a rogue exoplanet – NGTS-4b – with its own atmosphere in the Neptunian Desert. The Neptunian Desert is the region close to stars where no Neptune-sized planets are found. This area receives strong irradiation from the star, meaning the planets do not retain ..


TESS Mission of NASA discovers its first Earth-size planet – HD 21749c

The Transiting Exoplanet Survey Satellite (TESS) Mission of NASA has discovered its first Earth-size planet – HD 21749c. The newly-discovered planet is about 89% Earth’s diameter. The planet is likely very hot, with surface temperatures perhaps as high as 800 degrees F (427 degrees C). It orbits HD 21749, a K-type dwarf star located 53 ..
